[#454030] distutils cannot link C++ code with GCC
topdir = "Lib/distutils"
* bcppcompiler.py
(BCPPCompiler.create_static_lib): Fixed prototype, removing extra_preargs
and extra_postargs parameters. Included target_lang parameter.
(BCPPCompiler.link): Included target_lang parameter.
* msvccompiler.py
(MSVCCompiler.create_static_lib): Fixed prototype, removing extra_preargs
and extra_postargs parameters. Included target_lang parameter.
(MSVCCompiler.link): Included target_lang parameter.
* ccompiler.py
(CCompiler): New language_map and language_order attributes, used by
CCompiler.detect_language().
(CCompiler.detect_language): New method, will return the language of
a given source, or list of sources. Individual source language is
detected using the language_map dict. When mixed sources are used,
language_order will stablish the language precedence.
(CCompiler.create_static_lib, CCompiler.link, CCompiler.link_executable,
CCompiler.link_shared_object, CCompiler.link_shared_lib):
Inlcuded target_lang parameter.
* cygwinccompiler.py
(CygwinCCompiler.link): Included target_lang parameter.
* emxccompiler.py
(EMXCCompiler.link): Included target_lang parameter.
* mwerkscompiler.py
(MWerksCompiler.link): Included target_lang parameter.
* extension.py
(Extension.__init__): New 'language' parameter/attribute, initialized
to None by default. If provided will overlap the automatic detection
made by CCompiler.detect_language(), in build_ext command.
* sysconfig.py
(customize_compiler): Check Makefile for CXX option, and also the
environment variable CXX. Use the resulting value in the 'compiler_cxx'
parameter of compiler.set_executables().
* unixccompiler.py
(UnixCCompiler): Included 'compiler_cxx' in executables dict, defaulting
to 'cc'.
(UnixCCompiler.create_static_lib): Included target_lang parameter.
(UnixCCompiler.link): Included target_lang parameter, and made
linker command use compiler_cxx, if target_lang is 'c++'.
* command/build_ext.py
(build_ext.build_extension): Pass new ext.language attribute
to compiler.link_shared_object()'s target_lang parameter. If
ext.language is not provided, detect language using
compiler.detect_language(sources) instead.
* command/config.py
(config._link): Pass already available lang parameter as target_lang
parameter of compiler.link_executable().
customize_compiler() now looks at various environment variables and uses
their values to override the configured C compiler/preprocessor/linker
binary and flags.
whether the Distutils being used supports a particularly capability.
(This idea was originally suggested by Juergen Hermann as a method
on the Distribution class. I think it makes more sense as a
function in core.py, and that's what this patch implements.)
arguments, triggering a warning instead of raising an exception. (In
1.5.2/2.0, it will print to stderr.)
Bugfix candidate for all previous versions. This changes behaviour,
but the old behaviour wasn't very useful. If Distutils version X+1
adds a new keyword argument, using the new keyword means your setup.py
file won't work with Distutils version X any more.
Strangely, two out of three patches there seem already committed; but
the essential one (get rid of the assert in object_filenames in
ccompiler.py) was not yet applied.
This makes the build procedure for Twisted work again.
This is *not* a backport candidate despite the fact that identical
code appears to exist in 2.2.2; Twisted builds fine there, so there
must have been a change elsewhere.
The default implementation calls _compile() to compile individual
files. This method must be implemented by the subclass. This change
factors out most of the remaining common code in all the compilers
except mwerks.
Two new tests are needed:
Don't skip building an extension if any of the depends files are newer
than the target.
Pass ext.depends to compiler.compile() so that it can track individual
files.
Always use _setup_compile() to do the grunt work of processing
arguments, figuring out which files to compile, and emitting debug
messages for files that are up-to-date.
Use _get_cc_args() when possible.
This change is not backwards compatible. If a compiler subclass
exists outside the distutils package, it may get called with the
unexpected keyword arg. It's easy to extend that compiler by having
it ignore the argument, and not much harder to do the right thing. If
this ends up being burdensome, we can change it before 2.3 final to
work harder at compatibility.
Also add _setup_compile() and _get_cc_args() helper functions that
factor out much of the boilerplate for each concrete compiler class.
Remove __init__ that just called base class __init__ with same args.
Fold long argument lists into fewer, shorter lines.
Remove parens in tuple unpacks.
Don't put multiple statements on one line with a semicolon.
In find_library_file() compute the library_filename() upfront.
